Abstract: A system and method for facilitating adjusting a displayed representation of a visualization. An example method includes displaying a first visualization that includes plural nodes; providing a first user option to specify a first node attribute; and stacking nodes of the first visualization based on the first node attribute, resulting in display of one or more stacks of nodes. In a more specific embodiment, one or more links connect one or more of the plural nodes to one or more other nodes of the plural nodes. The method further includes adjusting the first visualization to illustrate the one or more stacks of nodes, while preserving any links, resulting in display of a second visualization in response thereto. The step of adjusting further includes animating a transition between display of the first visualization and display of the second visualization.

Abstract: A system for generating audio impressions of data for a visually-impaired user. The system receives data that is displayable by a chart. The data comprises a plurality of values. The system generates an audio impression of the received data. The audio impression includes a first portion and a second portion. The first portion is based upon at least a first value of the received data. The second portion is based upon at least a second value of the received data. An audible difference between the first portion and the second portion reflects the magnitude of a difference between the first value and the second value.

Abstract: A markup programming technique is described which directs a rendering agent to display at least two charts at the same time and, in response to a cursor operation over one of the charts, to replace the other chart. The cursor operation need not be a mouse click and can simply be the event of moving the cursor into a specified area of the first chart.
